Abstract
Disclosed herein is a process and apparatus for grinding tooth surfaces of spur and helical gears by a generating method. The outer tooth surfaces of a theoretical ring gear are conjugate to the grinding surfaces along the width of a generally hourglass shaped grinding wheel. The grinding wheel is rotated which in turn causes the theoretical ring gear to rotate. A work gear is rotated in mesh with the internal tooth surfaces of the theoretical ring gear and simultaneously is traveresed in mesh across the width of the grinding wheel with the center of the work gear moving in a path about the center of the theoretical ring gear.
